    A perfect clutch is just that, perfect and without noises or vibrations. I am beginning to wonder if you may have a dual mass flywheel on the way out........
  2. JFP in PA
    You need to be careful here. Porsche like to use "single use" barbed connections on the fuel lines, which require cutting the flexible hose off to remove. Once you have done that, the hose section will be shorter, and may no longer reach where the fitting needs to be, or keeps too much tension on the connector, leading to its failure and a sudden large fuel leak in a hot engine bay. You would be better off replacing the entire flex line section with a new one.

    There are several sensors that can prevent the AC compressor from running; low pressure, high pressure, high temperature, dead compressor clutch. First thing I would look at is by passing the system and try triggering the compressor using a safe voltage probe such as the Power Probe tool. If the clutch engages and the system cools, the problem lies in the sensors, if it doesn't engage, you have a compressor issue. Very few people field repair compressors anymore, cheaper and quick to replace it.
  4. JFP in PA
    How big a compressor is based upon what you are going to use it for. For your purposes, one of the 110V "pancake" compressors should do fine: This unit is $60 on Amazon.

    We see a fair number of "knock off" coils, most of which cannot hold a candle to the OEM units and end up having to be replaced prematurely. They are cheap for a reason, and not a good one.
  6. JFP in PA
    Yes.
  7. JFP in PA
    Well, to begin with, unless you have gotten air into the ABS/PSM system, you really do not need to activate the pump.
  8. JFP in PA
    It may, but it is not a guarantee. There may be other issues as well, or it may just be low on fluid from leaking.
  9. JFP in PA
    Yes, these parts will work on a 2000, it uses the same oil pump. Be sure to also order a new crush ring for the plug that holds it in place.
  10. JFP in PA
    No, it is not a sensor, it is the spring and piston that control the actual oil pressure level leaving the oil pump and entering the engine oil passages. Fortunately, because of the design of the M96/97 engine, the plug holding the piston and spring in place is exposed on the oil pump, making replacing this a 5 min. proposition. The spring is slightly longer, which boosts the pressure, and the piston has a bevel on top that keeps it from getting stuck in the bore. A simple low cost update that make your engine happy

    Welcome to RennTech. I seriously doubt the torque convert is at fault here; it is most likely a front seal issue.Unfortunately, as I mentioned above, Porsche only lists compete replacement transmissions for your car. To find a replacement front seal, you are going to need to pull yours and then check with VW, Audi, or MB dealers to see if they can match up one from their transmissions. You might also consider contacting local transmission repair shops to see if they can help.
  12. JFP in PA
    Sorry, but from extensive experience, "not messing" is bad advice. These pumps age and the composite impellers become brittle and break up, clogging small coolant passages and become nearly impossible to remove.
  13. JFP in PA
    Welcome to RennTech. Could be a couple of things; a fuse is possible, or a weak or failing ignition switch. You are going to need to do some "poking around" diagnostics.
  14. JFP in PA
    What water pump did you use (brand/impeller material type)?
  15. JFP in PA
    All these parts have been superseded with upgraded pieces: Piston 997.107.125.01 Spring 996.107.127.53 Gasket 996.107.123.50 So for less than $20 at retail, you get better low RPM oil pressure. The new piston also has a bevel on its upper edge as well, and the spring is slightly longer:
  16. JFP in PA
    LN make the nicest ones that I have seen, and we have never had any problems with their products.
  17. JFP in PA
    You might say we have had good results; I have many of my customers on them for several years now with excellent performance. I also use them on my personal fleet as well. One additional benefit ( amongst many) is that you can use a FilterMag with the spin on, so that every drop of oil passes through a strong magnetic field on every pass.
  18. JFP in PA
    Check the axle CV joints for excessive play.

    To change the chains, the engine has to come out and apart. So unless you can see a reason to do it, I'd leave them alone. A cam swap could have accelerated the wear pad issue. As you are already there, the solenoid would not be a bad idea.
  20. JFP in PA
    Welcome to RennTech. As yours is a five chain motor. the likely culprit are the small chain tensioner wear pads between the cams: While not a difficult job, it does require some specific tooling and knowledge of how the cams are times or "allocated" in Porsche speak. I'm pretty sure there is a DIY with photos over on the Pelican site for this specific project, but if you can get access to either the factory service manual or the Bentley 996 manual, you can find everything needed. Good luck.

    If you actually have a bad head gasket (which I cannot see in the photos), you would be the very first head gasket I have ever seen fail on one of these engines. By far, the two biggest reasons for intermix on an M96/97 are cracked cylinder heads, or cracked cylinder liners:
  22. JFP in PA
    Both systems show hours, you need to calculate the miles based upon assumed averages.
  23. JFP in PA
    Durametric also shows it.
  24. JFP in PA
    The system does not work that way. The security system in the car is coded to match the key and its buttons, which requires having the key codes and access to a PIWIS system to enable the coding. I am unaware of anyone that sells the electronics package that goes into the keys other than buying a new one from Porsche and then having them code the car to match. Aftermarket or used stuff will not work without all the correct code information, and then the car still has to be coded to accept it. Be ready to spend some $ for all this.

    Take the battery to an auto parts store and have it load tested; it sounds weak.
